What is a Hookify rule?

A Hookify rule is a Markdown file with YAML frontmatter that defines specific patterns (using regex) for Claude to monitor during bash commands, file edits, or prompt submissions.

How do I test a new Hookify rule?

Rules are read dynamically by Claude. Once you save the .local.md file, the rule is active and will trigger on the next relevant tool use or event match.

Can I prevent Claude from executing certain commands?

Yes, by setting the 'action' field to 'block' in the YAML frontmatter, you can prevent specific operations or commands from proceeding when a pattern match is detected.

Where are Hookify rules stored in a project?

Rules are stored in the .claude/ directory within your project root, following the naming convention .claude/hookify.{rule-name}.local.md.

Productivity & Workflow

Automates the creation and configuration of Hookify rules to enforce coding standards, security guardrails, and project-specific workflows.

The Hookify Rules skill provides a standardized framework for defining custom behavioral triggers for Claude using Markdown and YAML. It allows developers to set up specific patterns—such as dangerous bash commands, sensitive file edits, or pre-completion checklists—that prompt Claude with guidance or warnings in real-time. By utilizing regex-based matching and multi-condition logic, this skill ensures consistency across a codebase, prevents high-risk errors like committing API keys or executing destructive commands, and streamlines development through automated project-specific instructions.
